This invention relates to mouthpieces for tobacco pipes, cigarette tubesand the like hereinafter referred to as pipes.

Mouthpieces of pipes are normally provided at 5 theend of the tail witha lip which, when the pipe is in use, normally abuts against the back ofthe teeth to prevent the pipe from falling out of the mouth. This lipconsists of a raised portion or flange which extends around thecircumference of the endof the tail of the mouthpiece and due to thislip and to the normal rounded or curved surface of the tail,'it isuncomfortable and indeed extremely difficult for a smoker to smoke hispipe so that the bowl isright to the side of the face, which position ofthe bowl is sometimes desirable to obtain a firm grip of themouthpiece'by the teeth and to keep smoke from the bowl away from theeyes. This positioning of the pipe during smoking is particularlyadvantageous for smokers with dentures.

According to the present invention, the tail of the mouthpiece is formedsubstantially fiat on the top and bottom surfaces and is provided at oradjacent its end on one or both surfaces with a projection or button thewidth of which extends only for a short distance on either side of thecentre line of the mouthpiece in lieu of the normally provided lip.

The projections or buttons may be of any desired shape, e. g.,substantially rectangular in plan and substantially triangular inelevation with one surface vertical or circular or elliptical and arepreferably positioned on both surfaces diametrically opposite oneanother adjacent the tail of the mouthpiece, whilst more than oneprojection or button may be provided on one or both surfaces of themouthpiece.

The mouthpiece may, moreover, be continued as substantially fiat to apoint adjacent that end of the mouthpiece which fits into the stem ofthe pipe.

Various examples of mouthpieces for tobacco pipes are shown in theaccompanying drawing,

in which:

Figures 1 and 2 are respectively a side elevation and plan of one formof mouthpiece fitted to a Figures 3-22 inclusive show similar views ofmodified forms of mouthpieces.

In the drawing the mouthpieces I are formed substantially fiat on boththe top and bottom surfaces and as shown in all of the figures with theexception of Figures 3-6'and 17-22 are provided on both surfaces with aprojection or button 2. In Figures 1 and 2 the buttons rise from the endof the mouthpiece, which in all cases is not provided with the usuallip, in the shape of an arc of a circle for a short distance and then isbrought down to the mouthpiece at a right angle thereto to form a rightangled projection against which the back surfaces of the teeth canengage, the two buttons being identical.

In Figures 3 and 4 only one button is provided the mouthpiece instead ofbeing arcuate in 2 contour.

The mouthpiece shown in Figures 7 and 8 differs from that shown inFigures 1 and 2 only in that the button is longer and hence the diameterof the circle on which the arc is struck is greater.

In Figures 9 and 10 a mouthpiece is shown in which the button on the topsurface is substantially similar to that in Figures 7 and 8 whilst thebutton on the bottom surface is reversed so that the front surface ofthe teeth in the lower jaw abut against the right angled projection.

In Figures 11 and 12 the top button is spaced away from the end of themouthpiece similarly to that shown in Figures 5 and 6 whilst the lowerbutton merges into the end of the mouthpiece.

In the arrangement shown in Figures 13 and 14 the top button is similarin shape and position to that provided on the top surface of themouthpiece shown in Figures 1 and 2, whilst the lower button is largerthan the upper and is substantially similar to that shown on the lowersurface ofthe mouthpiece shown in Figures 7 and 8.

In Figures 15 and 16 a button similar in shape but slightly larger thanthat shown in Figures 5 and 6 is provided on both surfaces, the buttonshowever being spaced away from the end of the mouthpiece.

In Figures 17-20 two different forms of mouthpieces are shown in whicheach is provided on both upper and lower surfaces with three buttons orprojections. In Figures 17 and 18 the lower part of the middle button isnot carried down to the mouthpiece but merges into the adjacent buttonswhich themselves meet the mouthpiece, so

that the buttons may be said to form a single button but with aplurality of upward projections or teeth, whilst in Figures 19 and 20the three buttons are separate from one another.

In Figures 21 and 22 the top surface of the mouthpiece is formedsimilarly to that shown in Figures 17 and 18 whilst the lower surface isprovided only with two buttons which merge into one another.

Owing to the absence of a lip and to the flat formation of the tail ofthe mouthpiece as con-s structed in accordance with this inventionitiisfound possible to obtain a firmer grip of the mouthpiece with the teethand also "no matter what be the angle of the bowl with respect to themouth, since it is possible for the teeth to grip the mouthpiece inarcuate manner conforming to the natural are of the teeth, theprojections or buttons not being positioned so as to give rise to anuncomfortable feeling for the lips or teeth, but merely preventing thepipe from falling from the mouth, since it is possible'for thev buttonsor projections to lodge in the V formed by two adjacent teeth, which ofcourse is impossible with mouthpieces provided with the normal lip. Withmouthpieces as generally constructed at the present time dentures comeup against the lip and due to the mouthpiece being usually of greatestheight in the middle and tapering off at the sides, the dentures slipoif.

Furthermoraby varying the position of the buttons or projectionsprovided in accordance with this invention, a mouthpiece may readily beprovided which is comfortable for smokers having an overlapping orprotruding upper or lower jaw, particularly when the buttons orprojections are provided on the centre line of the mouthpiece. 3

distance on either side of the centre line on said surface in lieu ofthe normally provided lip and being substantially less than the width ofthe mouthpiece.

2 A mouthpiece for tobacco pipes, cigarette tubes and the like whichover a considerable portion of its length is formed substantially fiaton the top and bottom surfaces at least one projec- 7 tion beingprovided at the end and raised from they general plane of saidmouthpiece on both said top and bottom surfaces, the width of theprojectionsbeing substantially less than the width of the mouthpiece andextending only for arshort distance on either side of the centre line ofthe said surfaces in lieu of the normally provided lip.

4. A mouthpiece as claimed in claim 2 in which three projections areprovided on both the top and bottom surfaces said projections beingdiametrically opposite oneanother.

5. A mouthpiece as claimed in claim 2 in which the projections aresubstantially triangular in cross section, the apex of the trianglepassing towards the bowl end of the mouthpiece.
